Inclusion criteria
* Medically stable on the basis of physical examination, medical history, and vital signs, performed at screening. Any abnormalities must be consistent with the underlying illness in the study population and this determination must be recorded in the participant's source documents and acknowledged by the investigator * Must have had UC diagnosed prior to screening * Have moderately to severely active UC, defined as a baseline Mayo score of 6 through 12, inclusive, with a screening Mayo endoscopy subscore greater than or equal to (\>=) 2 as determined by a central review of the video of the endoscopy * A participant who has had extensive colitis for \>= 8 years, or disease limited to the left side of the colon for \>= 10 years, must: a) have had a full colonoscopy to assess for the presence of dysplasia within 1 year before the first administration of study intervention or b) have a full colonoscopy with surveillance for dysplasia as the baseline endoscopy during the screening period. Results from these surveillance biopsies must be negative for dysplasia (low-grade, high-grade, or indeterminant) prior to the first administration of study intervention * Females of childbearing potential must have a negative highly sensitive urine pregnancy test at screening and at Week I-0 prior to study intervention administration
Exclusion criteria
* Have UC limited to the rectum only or to less than (\<) 20 centimeter (cm) of the colon * Presence or history of colonic or small bowel obstruction within 6 months prior to screening, confirmed by objective radiographic or endoscopic evidence of a stricture with resulting obstruction (dilation of the colon or small bowel proximal to the stricture on barium radiograph or an inability to traverse the stricture at endoscopy) * Have a history of latent or active granulomatous infection, histoplasmosis, or coccidioidomycosis, or have had a nontuberculous mycobacterial infection prior to screening * Presence or history of any malignancy including presence or history of lymphoproliferative disease including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy of unusual size or location (example, nodes in the posterior triangle of the neck, infraclavicular, epitrochlear, or periaortic areas) and monoclonal gammopathy of undetermined significance, or clinically significant hepatomegaly or splenomegaly * Has known allergies, hypersensitivity, or intolerance to ustekinumab or its excipients
Design outcomes
Primary

| Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability | Up to 74 weeks | An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. |
| Number of Participants with Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability | Up to 74 weeks | SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect, and suspects transmission of any infectious agent via a medicinal product. |
| Number of Participants with AEs Leading to Discontinuation of Study Intervention | Up to 74 weeks | Number of Participants with discontinuation of study intervention due to an AE, infections, injection-site reactions, and AEs during or within 1 hour of an infusion will be reported. |
| Number of Participants with AEs of Special Interest (AESI) as a Measure of Safety and Tolerability | Up to 74 weeks | AESI of any newly identified malignancy, case of active tuberculosis (TB), or opportunistic infection occurring after the first administration of study intervention(s) in participants will be reported. |
| Number of Participants with Laboratory Abnormalities | Up to 74 weeks | Number of participants with laboratory abnormalities related to hematology, serum chemistry, and coagulation will be reported. |
| Reactions Temporally Associated with an Intravenous (IV) Infusion and Subcutaneous (SC) Injection-site Reactions | Up to 74 weeks | Reactions temporally associated with an IV infusion (induction period) and SC injection-site reactions (maintenance period) will be reported. |
| Serum Concentration of Ustekinumab | Up to 74 weeks | Serum samples will be analyzed to determine concentrations of ustekinumab. |
